APPARATUS FOR TREAT-INGRESPIRATORY DISEASES.

SPECIFICATION forming part of Letters Patent No. 651,962, dated June 19, 1900.

Application filed May 4, 1898. Serial No. 679,716. (No model.)

To all whom it may concern:

Be it known that I, DEMETRIUS BOGHEAN, a subject of the King of Roumania, residing at Vienna, Empire of Austria-Hungary, have invented a new and useful Apparatus for the Treatment of Respiratory Diseases, of which the following is a full, clear, and exactdescription.

The present invention consists of an apparatus for the treatment of respiratory diseases by means of which the breathing of a patient may be regulated both as regards the periods of time in whichthe breath is drawn and the depth of the same.

In order to render the specification more easily intelligible, reference is had to the accompanying drawings, in which similar let-.

ters of reference denote similar parts throughout the several views.

Figure 1 is a sectional plan of one form of the invention; Fig. 2, a similar plan of a modified form; Fig. 3, a similar plan of a further modification; Fig. 4, a sectional side elevation of a device for tightening and loosening the regulating-band, and Fig. 5 a front elevation of Fig. 4.

According to the invention a cord or band is employed in connection with the patient, said cord or band being arranged around the chest of the patient and periodically tightened to produce the expiration and periodically loosened to allow of relaxation of the chest and lungs, (inspiration) The .band does not actdirectly on the b0dy,-bnt is employed in combination with a series of plates or cushions, which are fitted properly to various parts of the chest and back, according to the nature of the disease to be treated.

In the drawings, according to Fig. 1, plates or cushions b b b are fitted, the former advantageously to the back and the latter to parts of the chest. These plates are connected by means of a cord or band (1, adapted to run on 1 the ends of said bands being attached to a drum 6, Fig. 4, which is periodically turned a certain portion of a revolution and then reshows the side wings or plates Z) 6 hinged to the breastplate b the back-plate I) being the same shape in all cases.

The means for periodically contracting or drawing together the cord or band, and thus producing respiration, may be of any kind whatever. An electric motor is advantageous, as owing to the very small amount of power required it may be mounted on the back plate or cushion b and carried by the patient. The drum e, Figs. 4 and 5, is mounted on a shaft 01, having a disk 2' in proximity to an eccentrically-mounted shaft f, having a disk 10. The disk 2 is provided with a campin g and the disk It with a cam-pin h. Thus if the latter disk is continually rotated by means of the electromotor owing to the eccentric position of this disk with regard to the disk t the two cam-pins h and 9 will remain in engagement during a part of the revolution of the disk It, as indicated at Fig. 5 from auto y. During the other part of the revolution the .disk '5 will be disengaged from the motor-disk is and will be returned to its initial position by the inspiration of the patient as he or she draws in breath. A stop Z is arranged on a stationary part of the machine to arrest-the disk 2' in its proper position when it is returned by the inspiration of the patient. The elec-' tromotor may be connected by suitably-long wires to any suitable source of electricity. The wires may be long enough to allow the patient suflicie'nt room for movement. In the event of a number of patients being supplied with electricity in a limited space for walking exercise the motor of each patient may. be connected to overhead conductors in the known manner.

From the above description it will be clear that the plates or cushions b may be adapted to any disease, according to requirement,their shape and the pressure of the cord thereon being variable to the finest degree. The periods of inspiration and breathing out may be varied at will by varying the number of revolutions made by the drivingpower motor. The plates will as a rule be sufficiently supported on the body by friction and the cord passing around the same, which is never entirely released. In the drawings the plates are indicated as being supported 'bya band passing along their inside, but they might be supported onth'e chair or bed of the patient;

.Itwill be obvious that the power for operating the device'may-be taken from any motor,

whether electrical-or other, that the breath ing periods may be varied at will, as also that the shape and position of the plates or cush ions may be varied to suit all kinds'of diseases which it is intended to cure by enforcing a regular breathing both as regards the depth and the length of breath. The depth will be regulated 'by the periods of engage-V ment of the motor-diskwith the apparatus disk, which also regulatesthe periods of res piration.

consists in not connecting the cord or band a direct to the plates or cushions, but in allow,- ing the same to. run over antifriction-rolls mounted on each plate.

Although themotor has been described as being advantageously mounted on the back plate 7), this need not necessarily be the case. It could be mounted at any other convenient point.

I claim as my invention 1. In an apparatus for regulating the breathiugof patients, the combination ofaseries of plates to fit various parts of the chest andv means for movably supporting the same, said, plates having guide-rolls mounted on their backs, a cord to pass over all the said guiderolls, and means for contracting said cord and allowing the same to expand periodically at regular intervals in the manner and for the purpose substantially as described.

12.".In an apparatus for regulating breathing the'combination of asingle plate to encompass the; back of the patient, said plate having guidewrolls on its outer surface, a series'of plates to ,fit the, various parts of the front of the chest, said plates also having guide-rolls thereon, a cord to pass over all theguides rolls and means for movably supporting the substantially as described.

saidplates and periodically contracting and allowing the said cord to expand at regular intervals, in the manner and for 3. In an apparatus for regulating breathing, the combinationof a series,ofpressure-plates to fitvarious parts of'the chest and means for movably supportin'gsaid plates, said plates having guide-rolls at the outer side of the same, a cord to pass around all the guide-rolls, a drum to which the ends of the said cord are attached and means for moving the disk positively in one direction and allowing it to be returned by the action of the chest of the patient in the manner and for the purpose sub- A stantially as described. One of the main features of the invention 4. In an apparatus for regulating breathing, the combination of a series of plates to fit various parts of the chest and means for movably supporting said plates, said plates hav- "ing guide-rolls at the back thereof, a cord to pass over said guide-rolls,- a drum at the back of the patient to the periphery of which the ends of the said cord are attached and means for positively reciprocating the said drum in one direction consisting of a disk mounted ,on the spindle of thesaid drum and having a pin projecting from its face nearthe periphery of the same, an eccentrically-mounted disk and a shaft to support the same, said eccentrically-mounted disk having a pin near the edge of its face and projecting therefrom and being mounted in proximity to the said disk on the cord-shaft, said'pins being adapted to contact and couple during a part of each revolution of the shaft of I the eccentricallymounted disk in the manner and for'the purpose substantially as' described.

, In witness whereof I have hereunto set my hand in presence of two witnesses.

DEMETRIUS BOGHEAN.
